ST. LOUIS (AP) – Icy conditions are blamed for several morning rush hour accidents in the St. Louis region.

Ice formed overnight, causing interstate highways to be slippery in spots Monday morning. The biggest of the accidents was a five-vehicle wreck on Interstate 64 near downtown. At least two other accidents snarled traffic on I-64, causing delays in both directions.

More than a dozen accidents were reported by shortly after dawn, including wrecks on Interstate 55 and Interstate 70.
